Suspension of the Jones Act and U.S. Gasoline Prices

Introduction to the Cabotage Regulatory Framework

The regulatory architecture governing the domestic maritime waters of the United States is fundamentally defined by Section 27 of the Merchant Marine Act of 1920, universally recognized in legal and economic spheres as the Jones Act. Enacted in the immediate aftermath of World War I under the sponsorship of Senator Wesley L. Jones, the legislation was engineered to prevent a recurrence of the acute logistical vulnerabilities the United States experienced when foreign shipping capacity was abruptly withdrawn from U.S. commerce to serve foreign war efforts. The law represents the cornerstone of American cabotage, a protectionist trade mechanism that reserves the transportation of goods within domestic borders exclusively for domestic entities.

The statutory requirements of the Jones Act are exceptionally rigid. The law mandates that any merchandise transported entirely by water between two points within the United States, including noncontiguous states like Hawaii and Alaska, as well as territories such as Puerto Rico, must be carried aboard vessels that satisfy four distinct criteria.

Furthermore, the legislation extends the Federal Employer's Liability Act (FELA) to maritime workers, providing seamen injured during their employment the statutory right to bring civil actions against their employers with the guarantee of a jury trial.

Over the course of a century, the macroeconomic implications of the Jones Act have evolved into a subject of intense academic and political polarization. Proponents of the statute, including the Department of Defense, the United States Navy, the Maritime Administration (MARAD), and domestic labor unions, assert that the law is an indispensable pillar of national sovereignty and security. They argue that the captive domestic market sustains the shipyard industrial base required to construct and repair military vessels, while simultaneously preserving a pool of credentialed civilian mariners who serve as a critical auxiliary sealift force during global contingencies.

Conversely, a broad consensus of economists, energy market analysts, and trade experts characterize the Jones Act as a highly distortionary market barrier that inflicts profound deadweight losses upon the U.S. economy. By insulating the domestic maritime sector from the competitive pressures of the global shipping industry, the law has precipitated a severe contraction in fleet size, an aging vessel inventory, and astronomical transportation costs. These elevated freight rates artificially sever the natural economic linkages between U.S. commodity producers and domestic consumers, forcing highly inefficient supply chain adaptations.

This economic friction becomes acutely visible during periods of global geopolitical instability. In early 2026, the escalation of military conflict involving Iran resulted in severe disruptions to maritime traffic through the Strait of Hormuz, propelling international Brent crude oil prices above $119 per barrel and causing domestic retail gasoline and diesel prices to surge. As the White House and Congress evaluate mechanisms to shield American consumers from this energy shock, proposals to temporarily suspend or permanently repeal the Jones Act have rapidly gained political traction.

The Anatomy of the U.S. Domestic Maritime Fleet

To accurately evaluate the economic burden of the Jones Act, it is necessary to examine the physical operational capacity of the fleet that exists under its protections. The data indicates a domestic maritime sector that has experienced prolonged stagnation and contraction, resulting in a severely constrained supply of available tonnage.

Fleet Inventory and Carrying Capacity

As of the analytical baseline established in late 2025, data compiled by the Department of Transportation's Maritime Administration confirms that the active, privately-owned, oceangoing Jones Act fleet consists of approximately 93 vessels exceeding 1,000 gross tons. This represents a precipitous decline of more than 50 percent since the year 2000, underscoring the failure of the protectionist framework to stimulate industry expansion.

The composition of this remaining fleet is heavily biased toward liquid bulk energy transport, reflecting the geographic reality that waterborne shipping remains the only viable domestic option where overland pipelines do not exist or are operating at absolute maximum capacity.

The domestic tanker fleet, comprising roughly 54 active vessels, is the critical logistical artery for the coastwise movement of crude oil and refined petroleum products. However, this capacity is highly concentrated and geographically captive. Approximately 14 of these tankers are dedicated solely to transporting crude oil from the Alaska North Slope to refineries situated in Washington state and California, a deployment necessitated by the total absence of pipeline infrastructure connecting the Pacific Northwest to Alaskan oil fields. The remaining product tankers operate predominantly along the Gulf Coast and the Eastern Seaboard, transporting refined fuels to coastal distribution terminals where pipeline deliveries fall short of regional demand.

When contextualized globally, the scarcity of U.S. domestic shipping is stark. The international maritime fleet contains more than 7,500 oil tankers; thus, the Jones Act restricts domestic energy transport to less than one percent of the world's available shipping capacity. Furthermore, the technological capabilities of the domestic fleet are notably limited. There is currently not a single Jones Act-compliant tanker capable of transporting Liquefied Natural Gas (LNG). Consequently, while the United States is a global leader in natural gas production and export, noncontiguous regions such as Puerto Rico and Hawaii, as well as pipeline-constrained regions like New England, are legally barred from receiving waterborne shipments of domestic LNG and are forced to import their natural gas from foreign nations, including historical adversaries.

The Economics of Protectionism: Capital and Operational Costs

The statutory mandate that all Jones Act vessels must be built in domestic shipyards is the primary catalyst for the market's extreme cost inflation. United States commercial shipyards operate at a massive competitive disadvantage relative to the dominant shipbuilding consortiums in South Korea, Japan, and the People's Republic of China. Lacking the economies of scale, heavy industrial automation, deep supply chain clusters, and direct state subsidies enjoyed by their Asian counterparts, American shipbuilders produce vessels at an exorbitant premium.

Market data from maritime brokerages and investment banks indicates that constructing a standard medium-range (MR) product tanker in an Asian shipyard costs approximately $45 million to $50 million. In stark contrast, commissioning the exact same vessel specification from a U.S. shipyard requires a capital expenditure of roughly $210 million to $220 million, a premium of between 300 and 400 percent. For highly specialized vessels, such as the wind turbine installation vessels (WTIVs) required for offshore renewable energy projects, the capital disparities are even more profound, often costing hundreds of millions of dollars more and requiring years of additional construction time compared to foreign-built alternatives.

Beyond the prohibitive initial capital costs, the daily operational expenditures associated with running a Jones Act vessel are significantly inflated. Comprehensive historical analyses conducted by MARAD and the Government Accountability Office (GAO) have consistently demonstrated that operating a U.S.-flagged vessel is between 2.7 and 4.4 times more expensive than operating a comparable foreign-flagged ship. A U.S.-flagged commercial ship incurs an estimated $11.1 million in annual operating costs, compared to just $2.6 million for an internationally flagged vessel.

The dominant driver of this operational cost differential is labor. Crewing costs for U.S.-flagged vessels account for approximately 68 to 70 percent of total daily operating expenses, whereas crewing accounts for only 28 to 35 percent of the costs for foreign-flagged operators. This disparity is a direct reflection of the higher standard of living in the U.S. economy, stringent union wage requirements, and the comprehensive liability protections afforded to mariners under the Jones Act. Additionally, U.S. vessels are subject to rigorous regulatory compliance frameworks enforced by the Coast Guard and the Environmental Protection Agency, and domestic shipping companies face combined corporate tax rates that significantly exceed the nominal tax burdens borne by international shipping registries.

These extreme capital and operational cost burdens establish formidable barriers to market entry. Fleet owners are highly reluctant to invest over $200 million in a new domestic tanker when the long-term demand for coastwise fossil fuel transportation faces significant obsolescence risks over a standard 30-year vessel lifespan due to ongoing energy transitions. As a result, the domestic fleet relies on older, less fuel-efficient tonnage, and the chronic scarcity of available ships translates directly into massive freight premiums. Spot charter rates for Jones Act product tankers routinely fluctuate between $86,000 and $91,000 per day, representing an order of magnitude increase over the $8,952 per day averaged by internationally flagged MR tankers operating in similar geographic theaters.

Structural Distortions in U.S. Petroleum Distribution

The intersection of extreme domestic shipping costs and profound geographic supply-demand imbalances creates severe structural distortions within the U.S. petroleum market. To manage regional energy logistics, the Department of Energy divides the country into Petroleum Administration for Defense Districts (PADDs). The United States possesses immense crude oil extraction and refining capacity, overwhelmingly concentrated in PADD 3, which encompasses Texas, Louisiana, and the broader Gulf Coast. Conversely, the primary population and energy consumption centers are located on the East Coast (PADD 1) and the West Coast (PADD 5).

In a highly functional, frictionless energy market, basic economic arbitrage dictates that surplus crude oil and refined gasoline from the Gulf Coast would flow continuously to the East and West Coasts until price differentials equalized with the cost of transportation. However, the domestic overland pipeline network is severely constrained and incapable of managing this volume independently. The Colonial Pipeline system, which serves as the primary artery moving refined products from the Gulf Coast up the Eastern Seaboard, routinely operates at or near absolute maximum capacity. Furthermore, there is no interstate pipeline network capable of transporting refined gasoline from the Gulf Coast across the Rocky Mountains to the massive consumer markets in California.

Expanding this pipeline infrastructure to alleviate the bottlenecks has proven nearly impossible due to intense regulatory and legal hurdles. Federal permitting statutes, most notably the National Environmental Policy Act (NEPA), require exhaustive environmental impact statements that subject developers to years of litigation regarding indirect greenhouse gas emissions. Additionally, states have aggressively utilized their certification authority under Section 401 of the Clean Water Act to veto federally approved pipeline projects crossing their jurisdictions. These compounding regulatory obstacles led to the high-profile cancellations of multi-billion-dollar infrastructure projects, such as the Atlantic Coast Pipeline in 2020 and the Northern Access Project in 2024, ensuring that pipeline capacity remains structurally constrained.

With overland routes either maximized or legally blocked, waterborne maritime shipping should naturally serve as the marginal mode of transport to clear the market. Yet, the Jones Act renders domestic coastwise shipping so prohibitively expensive that it completely fractures the arbitrage mechanism. As a direct consequence of these inflated freight rates, it is frequently more economical for East Coast fuel distributors to import gasoline, jet fuel, and diesel across the Atlantic Ocean from refineries in Europe, or crude oil from Nigeria and Saudi Arabia, than it is to purchase and ship those identical products from Texas or Louisiana.

Simultaneously, Gulf Coast refiners find themselves effectively priced out of their own domestic consumer markets on the opposing coasts. Faced with localized oversupply, these producers export massive volumes of refined fuels to markets in Latin America, Europe, and Asia utilizing highly affordable foreign-flagged tankers. This bizarre economic dynamic, wherein the United States relies on foreign imports to supply its coastal populations while simultaneously exporting its vast domestic energy surplus to foreign nations, is the hallmark inefficiency of the Jones Act. It artificially fragments what should be a unified, resilient domestic energy market, resulting in duplicated global transportation routes and unnecessary vulnerability to international supply shocks.

The California-Bahamas Gasoline Detour: A Case Study in Cabotage Evasion

Nowhere is the absurdity of Jones Act-induced supply chain contortions more starkly evident than in the state of California during the mid-2020s. California (PADD 5) operates effectively as an "energy island." Completely lacking interstate pipeline connections for refined petroleum products from the Gulf Coast, the state relies entirely on its in-state refineries and waterborne imports to satisfy the largest automotive gasoline demand in the nation.

Over the past decade, California has experienced a severe contraction in its local refining capacity. This decline is driven by a combination of stringent state-level environmental regulations, aggressive carbon taxing structures, and steadily declining in-state crude oil production. The closure of the Marathon Martinez refinery in 2020, the conversion of the Phillips 66 Rodeo facility, and the high-profile shutdown announcements for the Phillips 66 Wilmington facility in late 2025 and the Valero Benicia refinery in April 2026 equate to an imminent loss of roughly 17 percent of the state's total refining capacity. Facing an acute, structural fuel deficit and retail pump prices that average substantially higher than the national mean, California must urgently source massive volumes of replacement gasoline.

The most logical supplier is the U.S. Gulf Coast, home to one of the world's largest concentrations of highly complex refining infrastructure. However, chartering one of the few available Jones Act product tankers to move gasoline directly from Texas, through the Panama Canal, and up to Los Angeles is financially ruinous, costing orders of magnitude more than international freight. To circumvent the protectionist restrictions of the Jones Act, energy traders and logistics firms have established an astonishing supply chain workaround, the Bahamas detour.

Under this logistical arrangement, gasoline refined in the U.S. Gulf Coast is loaded onto inexpensive foreign-flagged tankers and shipped approximately 1,100 to 1,300 nautical miles across the Gulf of Mexico to massive transshipment and storage hubs located in Freeport, Bahamas. Because the Bahamas is a sovereign foreign nation, this initial leg of the journey does not qualify as coastwise trade and therefore does not violate the Jones Act. The American gasoline is temporarily stored, often blended with other components, and then re-exported. It is loaded onto different foreign-flagged vessels for a 4,000 to 4,500 nautical mile journey through the Panama Canal and up the Pacific coast to offload in Los Angeles or San Francisco.

By late 2025 and into 2026, Bloomberg data revealed that more than 40 percent of all waterborne gasoline imported into California was routed through this Caribbean hub. While this circuitous, 5,500-mile indirect route incurs significant extra storage, terminal handling, and transit time costs, the total expenditure remains lower than the sheer cost of chartering a scarce domestic Jones Act vessel for a direct, uninterrupted voyage. This practice, which closely mirrors established methods used to supply the U.S. East Coast via Caribbean terminals, vividly illustrates how a law originally designed to promote localized maritime trade instead forces American-made fuel to physically exit the country simply to be transported to another American state.

Quantifying the Suspension Dividend: Macroeconomic Impacts on Fuel Prices

To move beyond anecdotal supply chain anomalies like the Bahamas detour, rigorous econometric modeling is required to accurately assess the macroeconomic toll of the Jones Act on U.S. energy prices and to project the potential financial relief of its suspension. The most authoritative and comprehensive recent quantification of these costs was published by economists Ryan Kellogg (University of Chicago) and Richard L. Sweeney (Boston College) through the National Bureau of Economic Research (NBER).

Focusing their empirical analysis on the years 2018 and 2019, a stable period predating the extreme demand destruction of the COVID-19 pandemic and the massive supply shocks of the Russia-Ukraine conflict, Kellogg and Sweeney constructed a sophisticated counterfactual model simulating the U.S. petroleum distribution network in the complete absence of the Jones Act. They utilized granular data on Gulf Coast export freight rates to estimate the baseline domestic shipping costs that would prevail if highly efficient, foreign-flagged vessels were legally permitted to engage in U.S. coastwise trade. The economists then allowed their algorithm to digitally "arbitrage" the price differences between the Gulf Coast and the East Coast whenever the spatial price differential exceeded the newly modeled, lower transportation costs.

The findings of the study conclusively demonstrate that the Jones Act artificially inflates fuel prices for coastal consumers. In a non-Jones Act environment, the economic model showed that millions of barrels of conventional gasoline, jet fuel, and ultra-low-sulfur diesel would rapidly shift from the Gulf Coast to the East Coast, systematically displacing expensive trans-Atlantic foreign imports. This influx of affordable, domestically refined supply would trigger significant, structural price reductions along the Eastern Seaboard.

The geographic distribution of these price decreases is highly logical. The East Coast savings would be most pronounced in the Lower Atlantic region (e.g., Florida, Georgia, South Carolina), which lies in closest maritime proximity to the Gulf refineries, yielding gasoline price drops of up to $0.76 per barrel and jet fuel drops of $1.60 per barrel. The savings diminish progressively as the vessels travel further north into New England, where the added nautical transit distance increases the baseline shipping cost.

Conversely, the Gulf Coast would experience a marginal price increase (averaging $0.30 per barrel for gasoline). This occurs because local Gulf Coast supply, which was previously trapped in the region and artificially depressing local prices, would be aggressively diverted to fulfill the highly profitable, newly accessible East Coast demand, thereby tightening the regional Gulf market.

In aggregate macroeconomic welfare terms, repealing the shipping restrictions of the Jones Act for petroleum products would generate massive financial windfalls for American consumers. The Kellogg and Sweeney study estimates that U.S. consumer surplus would increase by a staggering $769 million annually. However, this consumer gain is partially offset by a corresponding decrease in producer surplus. Gulf Coast refiners, who also function as the primary suppliers to the East Coast via the constrained Colonial Pipeline, would see their regional profit margins squeezed as unrestricted waterborne arbitrage erodes the artificially high, monopolistic prices they previously commanded in isolated East Coast markets. The model calculates that total producer surplus would decline by $367 million per year.

Ultimately, subtracting the producer losses from the consumer gains yields a net efficiency gain to the U.S. economy of $403 million annually for the petroleum sector alone. This figure is highly conservative, as it only measures three specific refined products and light crude oil. When analysts extrapolate the costs of the Jones Act across all sectors of the economy, including the shipment of agricultural products, lumber, steel, road salt, and consumer retail goods to highly dependent, noncontiguous areas like Hawaii, Alaska, and Puerto Rico, the total economic penalty is vast. The Organisation for Economic Co-operation and Development (OECD) estimates that the aggregate deadweight loss of the Jones Act restrains U.S. economic output by tens of billions of dollars, while targeted studies reveal the law costs the state of Hawaii an extra $1.2 billion annually and places a $367 million tax on food and beverage imports to Puerto Rico.

The disparity inherent in the Kellogg and Sweeney findings perfectly encapsulates the entrenched political economy of the Jones Act. The financial benefits of repealing or suspending the law are immense in aggregate but highly diffuse, amounting to savings of only a few dollars a year for hundreds of millions of individual consumers. Conversely, the costs of repeal are heavily concentrated among a small, highly organized, and politically powerful cadre of domestic maritime operators, shipyard owners, maritime labor unions, and specific energy producers who view the law as a vital shield for their profit margins and are willing to expend significant lobbying resources to ensure its preservation.

Second-Order Economic and Environmental Effects

The market distortions created by the Jones Act extend far beyond the immediate price of gasoline at the coastal pump; they generate profound second and third-order negative externalities across the broader U.S. infrastructure and environmental landscape. By rendering domestic maritime shipping prohibitively expensive, the Jones Act fundamentally alters the modal share of national freight transportation, actively incentivizing businesses to utilize less efficient forms of overland transit.

In a balanced transportation ecosystem, heavy bulk commodities and non-time-sensitive freight are optimally moved via coastal shipping, which offers the lowest cost per ton-mile and the highest fuel efficiency. However, because the Jones Act eliminates the viability of short-sea shipping for many domestic routes, immense volumes of commercial freight are artificially forced onto the national highway system and interstate rail networks. This heightened reliance on trucking and freight trains dramatically increases infrastructure maintenance costs due to accelerated wear and tear on roads, bridges, and rail lines.

Furthermore, this modal shift imposes severe environmental costs. Surface transportation, particularly heavy-duty trucking, produces exponentially higher greenhouse gas emissions per ton of cargo moved compared to waterborne shipping. The intensive overuse of the highway system also exacerbates severe traffic congestion, particularly along the I-95 corridor and other highways running parallel to U.S. sea lanes, generating enormous opportunity costs in the form of lost wages, delayed logistics, and reduced economic output. Additionally, forcing hazardous materials, such as crude oil and industrial chemicals, onto rail cars and trucks increases the statistical probability of highway accidents and catastrophic train derailments, presenting acute risks to public safety and localized environments. Economic analyses focused specifically on these externalities suggest that the environmental and infrastructure benefits accruing from the repeal of the Jones Act, through the expanded use of waterborne transport and the introduction of newer, highly efficient foreign vessels, could exceed $8 billion per year.

The 2026 Geopolitical Energy Shock and Suspension Proposals

Theoretical economic models regarding the inefficiency of the Jones Act transformed into matters of urgent national public policy in the spring of 2026. Following a severe escalation of direct military conflict involving the United States, Israel, and Iran in late February 2026, global energy markets were thrust into a state of extreme volatility. Iranian retaliatory strikes targeted commercial shipping lanes and vital energy infrastructure, resulting in the effective closure of the Strait of Hormuz, the world's most critical maritime chokepoint, which historically facilitates the transit of one-fifth of the globe's crude oil and liquefied natural gas.

The immediate macroeconomic fallout from this supply shock was severe. By March 2026, the price of Brent crude oil, the primary international benchmark, surged to $119.50 per barrel, reaching its highest echelon since the immediate aftermath of the Russian invasion of Ukraine in the summer of 2022. This massive upstream disruption transmitted rapidly through the downstream supply chain. Within weeks, the national average for retail regular gasoline climbed by roughly 20 percent to $3.58 per gallon, while isolated, import-dependent markets like California witnessed average prices breach $5.34 per gallon. Even more concerning for the broader economy was the spike in the price of diesel fuel, the essential power source for commercial 18-wheeler trucks, agriculture, and rail freight. Diesel prices jumped 28 percent to $4.83 per gallon, triggering immediate, cascading inflationary pressures on the cost of food and essential consumer goods.

Facing intense public outrage and the looming specter of recessionary inflation ahead of the November midterm elections, the Trump administration began urgently reviewing a comprehensive suite of policy mechanisms to curb energy prices. Alongside coordinating emergency Strategic Petroleum Reserve (SPR) releases with G7 nations, floating the suspension of federal gas taxes, relaxing summer fuel blend regulations, and exploring highly controversial export restrictions, the White House actively signaled its intent to issue an executive waiver to suspend the enforcement of the Jones Act.

The fundamental rationale for the proposed suspension was deeply rooted in the arbitrage theories outlined by economists. If the global supply of oil is artificially constrained by war, the United States must optimize its internal, domestic supply chain to protect consumers. Allowing vast fleets of foreign-flagged tankers to move surplus crude and refined petroleum products directly from the Gulf Coast to the energy-starved East and West Coasts, without navigating the astronomical costs, Bahamas detours, and limited availability of the 54 domestic Jones Act tankers, could theoretically eliminate transportation friction, balance regional inventories, and lower retail pump prices.

Political momentum accelerated rapidly. Senator Mike Lee (R-UT) leveraged the acute crisis to aggressively promote his legislative proposal, the "Open America's Waters Act" (S. 2043), which seeks to permanently repeal the Jones Act entirely, arguing that "chucking this outdated policy would be a great step to alleviate fuel prices for American families" regardless of the ongoing conflict in the Middle East. Lawmakers from noncontiguous regions also pleaded for relief; legislators in Guam formally petitioned the White House for an emergency waiver to protect the island's economic stability and national security readiness amidst what reports called the biggest oil disruption in history.

The Legal and Mechanical Realities of a Jones Act Waiver

While politicians, editorial boards, and the public often view waiving the Jones Act as a simple administrative action requiring a single stroke of the executive pen, the actual statutory architecture governing such waivers is extraordinarily rigid, complex, and highly restrictive. The Merchant Marine Act of 1920 does not contain inherent mechanisms for its own suspension; rather, waiver authority resides within a separate statute entirely, 46 U.S.C. § 501.

Historically, the power to waive the Jones Act evolved from wartime exigencies. On December 12, 1941, days after the attack on Pearl Harbor, President Franklin D. Roosevelt signed an Executive Order granting the Secretary of Commerce the authority to waive compliance with navigation laws "for war purposes," a standard later codified by Congress as being "necessary in the conduct of the war". Following the Korean War in 1950, the standard was broadened to "in the interest of national defense," a looser definition that allowed administrations to issue waivers for a variety of commercial and energy-related reasons over the subsequent decades.

Beginning with the aftermath of Hurricane Katrina in 2005, short-term administrative waivers became the standard federal response to severe natural disasters (including Hurricanes Rita, Sandy, Harvey, Irma, Maria, and Fiona) and extreme supply shocks (such as the 2011 Libyan crisis SPR release) to allow foreign vessels to rapidly reposition fuel to devastated coastal areas. However, intense political backlash and aggressive lobbying from the domestic maritime industry regarding the perceived overuse and commercial exploitation of these waivers prompted Congress to severely restrict the executive branch's authority in recent years.

Through strict amendments packaged into the National Defense Authorization Act (NDAA) of 2021, and further modified in 2023, the waiver process was significantly tightened, drastically reducing its utility as a rapid-response economic tool. Today, waivers can be granted through two primary pathways, both of which are strictly predicated on national defense requirements rather than general civilian economic relief:

Department of Defense (DoD) Mandated Waivers: The Secretary of Defense can request a waiver that the Secretary of Homeland Security (DHS) must grant automatically. However, the 2021 legislative amendments fundamentally altered the legal standard from a broad "in the interest of national defense" to a highly specific and restrictive requirement: the waiver must be absolutely necessary to "address an immediate adverse effect on military operations". Furthermore, the Secretary of Defense is mandated to provide Congress with a detailed report within 24 hours explaining precisely why the waiver is necessary and why alternative actions utilizing U.S. flag capacity were not feasible.

Discretionary DHS Waivers (Non-DoD Requests): For waiver requests originating outside the DoD (e.g., from the Department of Energy seeking to alleviate civilian fuel shortages or from private commercial entities), the Secretary of Homeland Security exercises discretionary authority. Crucially, however, the law now explicitly prohibits the issuance of such a waiver unless the Maritime Administration (MARAD) first conducts an exhaustive survey of the domestic market and formally advises DHS that there are absolutely no Jones Act-qualified vessels physically available to perform the required transportation.

Furthermore, these discretionary waivers are strictly limited in duration. By law, they can only be granted for an initial period of 10 days, extendable to an absolute maximum of 45 days with respect to "any one set of events". Broad, blanket waivers covering entire regions or prolonged crises are expressly prohibited; each request must be evaluated on a case-by-case, vessel-by-vessel, and voyage-by-voyage basis. Entities requesting a waiver must submit highly granular data, including the exact vessel name, its flag of registration, the precise cargo description, exact loading and delivery dates, preferred ports, and a sworn statement that the requester does not have a coastwise-qualified vessel under charter.

In the context of the 2026 Iran war oil shock, these legal constraints present massive, likely insurmountable administrative hurdles. Utilizing the automatic DoD pathway requires the administration to legally prove that high civilian gasoline prices and regional supply bottlenecks present an "immediate adverse effect on military operations," a stretch of statutory interpretation that would invite immediate litigation from maritime unions. Utilizing the civilian DHS pathway requires proving the total exhaustion of the Jones Act tanker fleet and limiting the relief to a narrow 10-to-45-day window. This timeframe is wholly insufficient to fundamentally restructure complex, continental energy supply chains or establish new, durable shipping contracts with foreign vessel operators. As prominent maritime legal scholars note, the strict time limits and elevated national defense standards have transformed what was once an unbounded political tool into "almost no tool at all," rendering a Jones Act waiver highly impractical for addressing sustained macroeconomic price shocks.

The Freight Market Paradox: Worldscale Rates and the 2026 Reality

Even if the Trump administration were to successfully navigate the legal labyrinth of 46 U.S.C. § 501 and issue a broad suspension of the Jones Act, the fundamental economic assumption underpinning the policy, that foreign ships will automatically provide cheaper transportation in the spring of 2026, must be critically scrutinized against actual, real-time maritime freight market data.

The global tanker market operates on a highly standardized, unified pricing benchmark known as Worldscale (WS). Because voyage costs fluctuate wildly based on nautical distances, specific port fees, canal transit tolls, and bunker (marine fuel) expenses, the Worldscale Association establishes a baseline "flat rate" for hundreds of thousands of specific point-to-point voyage permutations worldwide. This flat rate is calculated to ensure that the net daily revenue for the shipowner remains the same across all routes. Tanker owners and charterers then negotiate freight costs not in raw dollars, but as a percentage "point" of this flat rate.

In early 2026, the global tanker fleet is operating under unprecedented structural stress. The average age of the international oil tanker fleet has crept above 14 years, the oldest recorded in modern history, due to a massive dearth of newbuild deliveries and a collapse in ship recycling between 2023 and 2025. Simultaneously, global carrying capacity has been drastically reduced by two compounding geopolitical factors. First, stringent Western sanctions have forced nearly 18 percent of the global supertanker fleet (VLCCs) into a clandestine "shadow fleet" exclusively serving sanctioned states like Iran, Russia, and Venezuela, removing them entirely from the legitimate commercial market. Second, ongoing geopolitical violence and attacks by militant groups in the Red Sea have forced major shipping conglomerates to abandon the Suez Canal, routing vessels on the vastly longer journey around the Cape of Good Hope, which severely absorbs available ton-mile capacity.

This combination of an aging, structurally limited supply of legitimate vessels and extended voyage durations has pushed international tanker rates to multi-year highs. By early 2026, Very Large Crude Carriers (VLCCs) were commanding exorbitant charter rates upwards of $130,000 per day on the spot market.

Sam Norton, the Chief Executive Officer of the major domestic maritime carrier Overseas Shipholding Group (OSG), points out that this extreme global inflation effectively nullifies the theoretical financial benefit of a Jones Act waiver in the current geopolitical climate. Using the Worldscale framework, Norton demonstrates that in the hyper-inflated March 2026 market, chartering a foreign-flagged vessel to execute a U.S. domestic route is actually more expensive than utilizing a captive Jones Act vessel.

Norton's analysis reveals a critical economic paradox: while the Jones Act undeniably inflates domestic shipping costs during normal, stable macroeconomic periods (as conclusively evidenced by the Kellogg & Sweeney data modeling the 2018-2019 baseline), during periods of acute global maritime crisis, the captive domestic fleet can actually serve as an unintended financial hedge against international freight volatility. Suspending the Jones Act to allow foreign tankers into the domestic market in March 2026 would subject U.S. refiners to exorbitant WS410 international spot rates, paradoxically increasing the delivered cost of fuel from the Gulf Coast to the East Coast by roughly a penny per gallon.

The Mechanics of Cost Pass-Through at the Retail Pump

Even if the global freight market were to stabilize, and a suspension of the Jones Act successfully reduced wholesale transportation costs between the Gulf Coast and the consumer coasts, an additional economic barrier exists: the pass-through rate to the retail consumer is rarely perfectly elastic.

Academic studies evaluating the transmission of input cost shocks to retail fuel prices reveal significant firm-level heterogeneity. When maritime freight costs or crude oil prices fall, fuel suppliers and individual gas stations, especially those operating in highly concentrated local markets or premium locations, frequently absorb a significant portion of those savings to widen their profit margins, rather than passing the entirety of the cost reduction down to the consumer at the pump. Empirical data indicates that retail fuel prices are more cost-reflective (meaning savings are passed on more efficiently) only at self-service or "thrifty" stations operating in environments with high local competition. Conversely, when input costs rise (such as during an oil shock), the cost increases are passed onto consumers almost immediately and completely, a phenomenon frequently observed in logistics and B2B e-commerce through rapid fuel surcharges.

Therefore, an executive suspension of the Jones Act in the spring of 2026 would likely trigger immense political and legal friction, expend significant administrative capital, and yet deliver negligible, or potentially negative, financial relief to the American consumer, as international freight premiums and domestic retail markups absorb any theoretical arbitrage gains.

National Security and the Maritime Industrial Base

Given that the economic arguments overwhelmingly demonstrate that the Jones Act structural harms the U.S. economy, restricts energy distribution, and fails as an effective emergency relief valve, the question remains: why does the legislation possess such formidable and enduring political resilience? The answer lies entirely in the realm of national security and defense strategy.

The United States military relies heavily on the integration of civilian maritime infrastructure to project military power globally. Despite the utility of advanced cargo aircraft, approximately 95 percent of the heavy equipment, munitions, and supplies required by the armed forces during a major overseas conflict must be transported by water. The Department of Defense, the United States Navy, the Coast Guard, and the U.S. Transportation Command (USTRANSCOM) consistently testify before Congress that the Jones Act is the bedrock of America's strategic sealift readiness.

The national security rationale is predicated on several interconnected pillars. First, the law ensures the survival of a domestic shipyard industrial base. The commercial shipyards sustained by Jones Act construction orders are the same facilities required to build, maintain, repair, and modernize complex naval warships. Second, the domestic crewing requirement guarantees a steady, reliable supply of highly trained, U.S. citizen mariners possessing specialized security clearances. In times of war or national emergency, these civilian mariners are required to crew the government-owned, organically controlled vessels within the Ready Reserve Force and the Military Sealift Command. Finally, commercial domestic vessels and their associated intermodal transportation systems (terminals, cranes, tracking software) are legally integrated into defense logistics through the Voluntary Intermodal Sealift Agreement (VISA), allowing the military to requisition domestic civilian capacity instantly during a crisis.

Proponents of the law, including the American Maritime Partnership, argue that repealing or suspending the Jones Act would instantly subject the fragile U.S. maritime industry to predatory, state-subsidized competition, primarily from the People's Republic of China. China currently commands over 53 percent of the global commercial shipbuilding market, while the United States accounts for a mere 0.1 percent. Advocates warn that without a captive, legally protected domestic market, American commercial shipyards would rapidly face bankruptcy and collapse. This collapse would eradicate the drydocks, the supply chains for specialized marine components, and the highly skilled labor force required by the military, ultimately rendering the United States dangerously and unacceptably dependent on foreign powers, potentially strategic adversaries, for its logistical survival in wartime.

However, critics of the law, including defense analysts at the Cato Institute and the Center for Maritime Strategy, counter that the Jones Act is actively failing its own national security mandate. They argue that a century of extreme protectionism has not fostered a robust, innovative industry; rather, it has shielded shipbuilders from the competitive pressures necessary for modernization. The result is a microscopic, geriatric fleet containing vessels decades older than the global average, exorbitant construction costs that discourage new orders, and a documented, severe deficit of thousands of qualified mariners required for a sustained military conflict. In this view, the Jones Act is not a functional defense subsidy, but a catastrophic policy failure that has overseen the slow atrophy of American maritime power while simultaneously taxing the domestic economy.

Recognizing this profound decline, legislators and the executive branch have recently begun shifting their strategic focus from simply defending the restrictive statutes of the Jones Act to actively subsidizing the maritime industrial base to lower costs. The proposed SHIPS for America Act (S. 1541), reintroduced in 2025 with bipartisan support, attempts to address the staggering capital cost disparity not by opening the market to foreign competition, but by offering massive federal subsidies. The legislation proposes a 25 percent investment tax credit for modernizing domestic shipyard facilities and a 33 percent tax credit for constructing or repowering U.S.-built oceangoing vessels, alongside reforming the Title XI Federal Ship Financing Program.

Concurrently, the Trump administration's comprehensive Maritime Action Plan (MAP), released in early 2026, seeks to penalize foreign competition to level the playing field. The MAP proposes implementing universal port-of-entry fees on foreign-built vessels and expanding cargo preference laws to force more international trade onto U.S. flagged ships, attempting to artificially rebalance the economic scales in favor of domestic production without dismantling the core tenets of the Jones Act.

Strategic Conclusions and Policy Implications

The Merchant Marine Act of 1920 represents a fundamental, enduring collision between the principles of free-market economic efficiency and the imperatives of national sovereignty and military readiness. The empirical data is unequivocal: by legally restricting waterborne commerce to a severely limited, highly expensive, and aging fleet of U.S.-built vessels, the Jones Act inflicts billions of dollars in deadweight loss upon the American economy.

In the petroleum sector specifically, the law severs the natural economic arbitrage between the energy-rich Gulf Coast and the energy-hungry East and West Coasts. It forces absurd, highly inefficient logistical workarounds, most notably the 5,500-mile California-Bahamas gasoline detour, and artificially elevates consumer prices along the coastal population centers by structurally locking out affordable domestic supply.

Yet, utilizing the suspension of the Jones Act as a rapid-response macroeconomic tool to combat the acute geopolitical energy shocks of 2026 is fundamentally flawed in both legal mechanics and current market reality. The statutory mechanisms governing executive waivers (46 U.S.C. § 501) have been aggressively restricted by Congress, demanding near-impossible legal thresholds of immediate military necessity or absolute, verified fleet unavailability, all within impossibly tight 10-to-45-day timeframes that cannot accommodate supply chain restructuring.

More critically, the hyper-inflated state of the global tanker market in early 2026, driven by the removal of sanctioned shadow fleets, a lack of new shipbuilding, and prolonged route diversions due to Middle Eastern warfare, means that chartering foreign vessels on the spot market is currently more expensive than utilizing the captive domestic Jones Act fleet. Therefore, an administrative waiver issued today would not translate to financial relief at the retail gasoline pump.

Ultimately, the United States faces a profound strategic dilemma that cannot be resolved through emergency executive action. The Jones Act imposes unacceptable, compounding costs on civilian supply chains, environmental infrastructure, and consumer wallets. However, its sudden removal threatens to permanently eradicate the fragile remnants of the domestic maritime industrial base, presenting severe, unacceptable national security vulnerabilities in an era defined by great power competition and fragile global logistics. Achieving efficiency in domestic energy markets will require comprehensive, deliberate legislative reform, either through the targeted repeal of the U.S.-build requirement to rapidly lower capital shipping costs while maintaining domestic crewing and flagging for security, or through a massive transition to transparent, direct federal subsidies to maintain shipyard readiness without systematically crippling domestic commerce.
